"Save game at this point (BETA)" corrupted my game to disallow movement bonuses

Ok,
I understand the warnings about using the "save game at this point" in the game history mean it isn't always going to work, and this time it didn't. But the failure mode in this case seem bizarre. I'm playing the AA1940 global game that adds airbases and ports to the game, but the saved game does not add the movement bonuses to any units. The ports and airbases still are in the countries, but they don't do anything.

I'm curious to know if there is a simple edit I could make to the file to fix the problem, as it seems like some flag/option has been set inappropriately.

@jim-parker Yeah, the reason is that the airbase and naval bases use a trigger to add the +1 movement to air/naval units and this trigger may not fire properly when the game is saved from the history but as you can see once you play through a round everything should be fine.
